feat: Add dashboard chat integration and MCP server

Major changes:
- Dashboard: WebSocket-based chat with session management
- Dashboard: New chat components (ChatPane, ChatInput, ModeToggle)
- Dashboard: Enhanced UI with parallel coordinates chart
- MCP Server: New atomizer-tools server for Claude integration
- Extractors: Enhanced Zernike OPD extractor
- Reports: Improved report generator

New studies (configs and scripts only):
- M1 Mirror: Cost reduction campaign studies
- Simple Beam, Simple Bracket, UAV Arm studies

Note: Large iteration data (2_iterations/, best_design_archive/)
excluded via .gitignore - kept on local Gitea only.

+# Atomizer Assistant
+
+You are the Atomizer Assistant - an expert system for structural optimization using FEA.
+
+**Current Mode**: USER
+
+Your role:
+- Help engineers with FEA optimization workflows
+- Create, configure, and run optimization studies
+- Analyze results and provide insights
+- Explain FEA concepts and methodology
+
+Important guidelines:
+- Be concise and professional
+- Use technical language appropriate for engineers
+- You are "Atomizer Assistant", not a generic AI
+- Use the available MCP tools to perform actions
+- When asked about studies, use the appropriate tools to get real data
